  摘要：

  稳定的N-未取代的1H-1,4-苯二氮平（12a-l），在2位或9位具有羰基或其类似物，是通过在甲氧化钠存在下，从4-叠氮喹啉（13a-l）通过光反应制备的。已知没有羰基的N-未取代的1H-1,4-苯二氮平过于不稳定，无法分离。根据光谱数据，分离得到的苯二氮平（12）被认为是通过1-NH氢与2位或9位羰基氧之间的分子内氢键稳定，从而使其得以分离。

  With a view to probe the structure and function of G-protein coupled receptors the synthesis of functionalized 8-mercaptoquinoline derivatives and 2-(2-pyridyl)thiophenol was achieved. A fluorescence-based method for determining the affinity of these metal chelators toward zinc ions was developed.

  In search for inhibitors of gastric H+/K+-ATPase, 4-(phenylamino)quinoline-3-carboxamides were synthesized and evaluated for antisecretory activity against histamine-induced gastric acid secretion in rats. These compounds were synthesized by condensation of aniline derivatives with N-substituted 4-chloroquinoline-3-carboxamides, which were obtained from treatment of 4(1H)-quinolinone-3-carboxylic acid

  为了寻找胃H + / K + -ATP酶的抑制剂，合成了4-（苯氨基）喹啉-3-羧酰胺并评估了其对组胺诱导的大鼠胃酸分泌的抗分泌活性。这些化合物是通过将苯胺衍生物与N-取代的4-氯喹啉-3-羧酰胺缩合而合成的，后者是由亚硫酰氯处理4（1H）-喹啉酮-3-羧酸而获得的。大多数化合物抑制大鼠中组胺诱导的胃酸分泌。其中，N-烯丙基-4-（2-乙基苯基氨基）喹啉-3-羧酰胺（4h）是最有效的抑制剂，并且作为候选抗溃疡药的分布最佳。该化合物显示出可逆的K +竞争性胃H + / K + -ATPase抑制活性。

  A series of novel quinoline-3-carboxamide derivatives were synthesized and evaluated for their immunomodulatory activity. The compounds were tested in vitro for effects on spleen lymphocyte proliferation and TNF-alpha production by macrophage. Three compounds showed immunomodulatory profiles similar to and more potent than those of linomide and FR137316 and were selected for further pharmacological studies in vivo. (c) 2005 Elsevier Ltd.
